It works but your back is in danger...,
Verified Purchase(What is this?)
This review is from: Everlast Exercise Wheel Body Toner - Blue (Sports)
I have to say that it really makes your abs working, after only 3-4 days you can see and feel some result. The drawback is that I had a really dangerously strong back pain for 1 week after having used it. I suppose that other than the instructions that are included, you would need a trainer that tells you how to use it properly to not injure your back.
I'll try to re-sell it as soon as I have a chance.
